Q:I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.

Q:Hi My sons car has alloy wheels, and metal valve stems, there is a tiny leak between the valve stam and the alloy on one wheel, we are struggling to get anyone to repair at a reasonable cost. Would tyre weld make a permanent repair?. Some tyre specialists won't touch the wheel, one other wants to drill out the stem put in another, which sounds a bit drastic. Any other ideas?, is it feasible to get the metal valve stem replaced by a rubber version?. Apparently the metal ones get curbed and then start to leak.
On that year car the tire is tubeless and the valve stem should not be moving as it would if you had a tube type tire. If the valve stem is pushing in it means you drove on the tire while flat and probably ruined the tire as well as the valve stem. The tire must come off the rim to be inspected before blowing it back up and used. If you don't inspect the tire it will probably blow out at highway speeds and kill someone!
Q:My sprinkler valve I just put in leaks from the top knobs you turn to allow water to pass through to the 3 main pvc pipes. I turn the water on on the main water line, open the little black twisty knobs to allow the water to pass through to the irrigation lines, but water leaks out through all 3 black twisty knobs. What do I need to do?!?!?!
You are turning on electric valves, manually, with the bleeder valve (little black twisty thing). It is normal for this to happen. This valve can turn on and off a zone, but it also releases air from within the lines causing water to spit out with it. After the air is out, you can twist it down enough to stop the leak and still have that zone remain on.
Q:what is a foot valve? how does it look? what is the application in petrochemical companies?
A foot valve is simply a check valve. It is common use in a piping system at the pump suction side. By placing it this way when the pump stops operating, fluid won't flow back into the lower reservoir and the suction side of the pump is always full of liquid.
Q:what are the symptoms of bad egr valve??? My car is shaking on idle.. Tune up with all has already been done.
FIrst, locate remove and clean out your IDLE AIR CONTROL VALVE. This is the usual culprit. The EGR valve usually only need to be cleaned, as it gets clogged up with carbon. On may cars, I just disconnect them because they make the inside of the engine dirty. Using more modern spark plugs can lower emissions all by themselves. You can sometimes jolt the EGR back into shape by tapping on it with a hammer. Use Gum-out spray to clean your intake manifold out. It might just clean the EGR, too!
Q:I just dropped my 3rd valve slide from my trumpet on the ground. It fell with the curved end first. I can't see any dents and it doesn't look bent, but I oiled it and everything and it's really hard to move. Could it be bent? How can I fix it?
Be sure that it is aligned correctly when you place it back in the valve casing. When you are putting it back in, it has to turn until you hear a click, indicating that the valve guide has fallen in the right space. This aligns the valve with all the ports. (The valve guide is a small plastic piece located under the valve spring. This valve guide must snap into a little notch inside the casing. When it does, the valve will be perfectly aligned. You will know when the valve guide is in the right place because you will feel and hear a click and the valve will not rotate any longer.) After thorough cleaning, oiling, and correct valve placement, if you still notice it sticking, take it to a repair shop to have it chemically cleaned. They are typically very good and will ensure your trumpet is in proper playing condition.
Q:where are the proportion valves located on a 1991 buick skylark?
the valves are on the brake lines before they break away from the frame, or at least they should be. They are controlled by the computer though.
Q:ok im 17 and had really bad chest pains for like 2 years and the dr told me last year my valve was leaking and the pains have been getting worse what should i do?
Minor valve leaks are common - I'm 6'1 and I've got one and I lead a perfectly normal life. The chest pains are probably unrelated as a valve leak doesn't hurt, and a heart attack has additional symptoms which you haven't mentioned. It's probably working out too hard, atrophy, growing pains, or bad Mexican food. YES, see a doctor, always, but it's probably nothing. I get chest pains too (along with pains in other parts of my body - especially when my ex is around), and it's nothing.
Q:the valve stem?
you cant get used one out and re-use it they tear up when you remove them unless their the ones with the nuts on them that bolt in,pull in types cant be re-used ,any parts store sells those in a pack of 4 or most tire shops will give you one if you ask them for it,good luck
